实例

您可以像这样来循环遍历所有的服务器变量：

<%
for each x in request.servervariables
response.write(x & "
")
next
%>

下面的实例演示了如何查明访问者浏览器的类型、ip 地址等等：

you are browsing this site with:
<%response.write(request.servervariables("http_user_agent"))%>

your ip address is:
<%response.write(request.servervariables("remote_addr"))%>

the dns lookup of the ip address is:
<%response.write(request.servervariables("remote_host"))%>

the method used to call the page:
<%response.write(request.servervariables("request_method"))%>

the server's domain name:
<%response.write(request.servervariables("server_name"))%>

the server's port:
<%response.write(request.servervariables("server_port"))%>

the server's software:
<%response.write(request.servervariables("server_software"))%>
